Your ADF system determines what for your ground system?

• A. Altitude
• B. Bearing
• C. Ground speed
• D. Distance

Answer: (B)

The main idea being tested is what an ADF provides for navigation. An Automatic Direction Finder is used with a ground-based beacon (like an NDB) to tell you the direction to that beacon. In other words, it gives you the bearing from your aircraft toward the ground station. This directional information helps you navigate toward or around the beacon, but it does not tell you your altitude, how fast you’re moving over the ground, or how far away you are from the beacon. Altitude comes from the altimeter, ground speed from airspeed and wind data, and distance to the beacon requires a range measurement such as DME or GPS.
